本文介绍了一种使用SSD1306驱动器的128x64 OLED屏幕的初始化和绘图操作示例，演示了如何通过I2C接口与Arduino进行通信，包括像素、线条、形状的绘制以及文本显示和滚动效果。

重新初始化 wire 到 D5D6

Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET);

Wire.begin(14,12);

/*********************************************************************
This is an example for our Monochrome OLEDs based on SSD1306 drivers

  Pick one up today in the adafruit shop!

This example is for a 128x64 size display using I2C to communicate
3 pins are required to interface (2 I2C and one reset)
